Sorry, I read it, but couldn't remember. ;-)

I tink the CPU performance of a system which can handle DVB streams is
good enough to decode MP3. :)
The solution with PCM is good enough.

Yes, this is very good! 
This is the starting point for a real multi-user Video/Audio server. I
finally would like to use a blown up server to support at least 3
independend TVs connected to 3 DVB cards with independend OSDs and
remote control. So video/audio directly from the DVB card is a
requirement. A 4th DVB card with PW can be shared by all. I may even add
one more card for time-shifting. 
[BTW, does the DVB driver support interrupt sharing on the PCI bus? ]
Additionally kvdr will be used to feed a video projector with the best
quality image possible.

I'm still in the state of investigation of components. I first started
with multiple LPX sized boxes sharing datastore with Firewire/100BT. But
now I am leaning more to the central server because this is cheaper
finally an better to manage.

I wish you success. :) 
I am just starting and busy with the first steps and cannot contribute
much at the moment, except some ideas. ;-)
